fix(gateway): use LAN IP for WebSocket/probe URLs when bind=lan (#11448)

* fix(gateway): use LAN IP for WebSocket/probe URLs when bind=lan (#11329)

When gateway.bind=lan, the HTTP server correctly binds to 0.0.0.0
(all interfaces), but WebSocket connection URLs, probe targets, and
Control UI links were hardcoded to 127.0.0.1. This caused CLI commands
and status probes to show localhost-only URLs even in LAN mode, and
made onboarding display misleading connection info.

- Add pickPrimaryLanIPv4() to gateway/net.ts to detect the machine's
  primary LAN IPv4 address (prefers en0/eth0, falls back to any
  external interface)
- Update pickProbeHostForBind() to use LAN IP when bind=lan
- Update buildGatewayConnectionDetails() to use LAN IP and report
  "local lan <ip>" as the URL source
- Update resolveControlUiLinks() to return LAN-accessible URLs
- Update probe note in status.gather.ts to reflect new behavior
- Add tests for pickPrimaryLanIPv4 and bind=lan URL resolution

Closes #11329

* test: move vi.restoreAllMocks to afterEach in pickPrimaryLanIPv4

Per review feedback: avoid calling vi.restoreAllMocks() inside
individual tests as it restores all spies globally and can cause
ordering issues. Use afterEach in the describe block instead.
